Upvoted! I'm starting to get really sick of this community.
Mord's E is borderline-crazy as it is, unlike all of the abilities that you mentioned, there is no counterplay to it aside from staying away from him. Even then, its iffy. You can't dodge his E, you can't Windwall his E, you just take it. If you are within 700 range of Mordekaiser EVER you are taking an E to the face. The cast time is instant too, there is no escaping from it. Again, if he activates E while you are within range of him, even if you flash as soon as it happens, the mace will follow you and you will take damage. Mord is going to farm the minions and push the lane with his Q and W, and as soon as you are in range of his E he is going to E you and your minions. Hell, he can push you to your turret and stay safe. His shield should be full from spamming his Q and W at minion waves and E at you, so then he just runs up to your turret and smacks you and runs away. He can even tank a shot or two in the beginning of the game without taking any damage to his health because his shield.
The 700 range aoe E of instant smackdown is perfectly fine.
Its noobs like this doublelift guy that give Mordekaiser a bad name and it frustrates me lmao
